TECHNICAL FIELD

A polyurethane-polyorganosiloxane copolymer is useful in personal care compositions, such as hair care compositions and skin care compositions.

BACKGROUND

Silicone resins (such as MQ and MQ-T type resins) have been used as film forming agents in personal care compositions. These silicone resins may suffer from the drawback of providing insufficient abrasion resistance (resistance to wear off) to the personal care compositions, or in some other instances may be too brittle and develop cracks relatively easily. Polyurethanes are being used also for these applications. While they have better abrasion resistance they can suffer from inferior water resistance and other disadvantages as compared with silicone resins. There is an industry need for improved film forming agents for use in personal care compositions.

SUMMARY

This invention relates to a composition comprising a polyurethane-polyorganosiloxane copolymer and a carrier.

This invention also provides a method of using the polyurethane-polyorganosiloxane copolymer for treatment of such substrates. This invention further provides a method for using the the polyurethane-polyorganosiloxane copolymer as a film forming agent.

After the reaction step ii) as described above, optionally the reaction product can be treated with an additional end blocker. This additional end blocker, e), can be such that it leaves an additional reactive group on the copolymer after end blocking reaction, or it leaves an unreactive group on the copolymer after the end blocking reaction. Suitable such end blockers for starting material e) include but are not limited to alcohols such ethanol, propanol, butanol, carboxylic acids such as acetic acid, and alcohols and carboxylic acids containing aliphatic unsaturation. Thio-alcohols, hydroxylamines, glycol, amino acids, and amino sugars are also suitable as additional endblocking agents.

Starting material e), the additional endblocker may be added to react with this residual isocyanate.

A solvent may be added during the method to prepare the polyurethane-polyorganosiloxane copolymer described herein. Any organic compound that will dissolve the polyurethane-polyorganosiloxane copolymer and that is relatively unreactive towards isocyanate, and amine and/or carbinol compounds is suitable as a solvent.

The amount of solvent to be used depends on the properties of the polyurethane-polyorganosiloxane copolymer including structure, molecular weight, and the particular method of copolymer preparation, and can be 0 to 99%. Generally for higher molecular weight copolymers especially when a high torque mixing mechanim will not be used, solvent may be added to reduce the viscosity and make the system easier to handle during performance of the method to make the polyurethane-polyorganosiloxane copolymer. If the molecular weight is relatively low and/or high torque mixing equipment such as a twin screw extruder is used, no solvent needs to be used. When solvent is used, the amount may be 0 to 99%, alternatively 0 to 80%, alternatively 1% to 60%, and alternatively 5% to 50%, based on the combined weights of all starting materials used.

Example 4 (Comparative)

Comparison samples were prepared by either taking away the copolymer and replacing it with isododecane (Control in table 6), or by replacing the copolymer with a comparative film former, which was an MQ resin produced by Dow Corning Corporation commercially being used as a film former in similar types of formulations (MQ Resin (749) in Table 6).

Example 5—Evaluation of Samples Prepared in Examples 3 and 4

Hydrated collagen substrate samples were prepared by pulling hydrated collagen over polycarbonate blocks. The foundation compositions described above were coated onto the hydrated collagen using a 2 micrometer film gauge. The resulting coating had a thickness of 150 micrometers. Each foundation composition was allowed to dry overnight to form a foundation on the hydrated collagen. Using a Gardner abrasion tester fitted with an adhesive strip of the loop side of Velcro, each sample was insulted for either 50 or 20 cycles, depending on whether the film was dry or sebum was added. Three blocks were tested per foundation. Each foundation was tested dry, however some of the best performers were tested for sebum resistance which required adding a drop of artificial sebum to the foundation, and evenly spreading it out; and then waiting a minute before beginning the abrasion testing.

A Hunterlab colorimeter was used to measure the LAB (color) value for each block using 0.5″ diameter filter. Measurements were taken at 0, 4, 8, 12, 16, 20, 30, 40, and 50 insults. If using sebum the testing stopped at 20 insults. From this a ΔE was calculated to determine the total change in color.

Table 6 shows abrasion resistance test results, as measured by the amount of color changes.

Contact angle was measured on the samples by diluting the copolymers prepared in Reference Example 1 and Reference Example 2 in ethyl acetate, to form solutions that were 80% ethyl acetate and 20% copolymer. The solutions were then coated onto cleaned glass microscope slides using a 50 micrometer film gauge. Three slides were made for each sample, and the slides were allowed to dry overnight. A VCA Optima device was used to test the slides for both water and artificial sebum. For water, 2 microns of water was added to slides with each sample dried thereon. For sebum, 1 microliter of artificial sebum was added. One contact angle measurement was taken per slide for each water and artificial sebum.

Solution samples were prepared by diluting the copolymers prepared in Reference Example 1 and Reference Example 2 in ethyl acetate, to form solutions that were 80% ethyl acetate and 20% copolymer. The solution samples were coated onto 10 centimeter long latex elastic bands using a 50 micrometer film gauge. The latex bands were 0.33 millimeter thick specimens from Four D Rubber Co. Ltd. in United Kingdom, Red Latex Rubber: incolore solution. One band was coated per sample, and coated bands were allowed to dry overnight. Photos were taken the next day before any measurements. Films were then stretched to 200% of their original length (20 cm). Photos were taken again to capture any cracking or differences in shine. The shine test results are summarized in Table 7.

Example 5 shows that the foundation prepared from the personal care composition of this invention, which includes a polyurethane-polyorganosiloxane copolymer, has superior abrasion resistance to a foundation prepared using a composition with a conventional MQ resin film forming agent. Additional benefits include improved flexibility for comfort of wear, and shine.

Deionized water is added to the mixing vessel. In order to keep the active silicone loading constant throughout testing, the water level may be adjusted by adding water depending on the percent copolymer in the various emulsions used. With moderate agitation, the polyquaternium-10 is dispersed until fully dissolved. This is then heated to 75° C. and the PEG-150 pentaerythrityl tetrastearate is added with continual mixing. Heat is decreased to 40° C. and sodium lauryl ether sulfate, cocamide MIPA, cocamidopropyl betaine are added in that order. When completely incorporated, polyurethane-polyorganosiloxane copolymer emulsion is added to the base shampoo. The shampoo is mixed for 5-10 minutes and then Phenoxyethanol (and) Ethylhexylglycerin is added. The water loss is compensated for and the formulation is mixed for an additional 5 minutes. The final pH of the shampoo formulations are approximately 5.5-6.0.
